The subject of this article is to see if a spatial variation of horizontal to vertical spectral ratios (HVSRs) of microtremors can be regarded as a proxy of an irregulari [...]

Bogotá, a megacity with almost 8 million inhabitants is prone to a significant earthquake hazard due to nearby active faults as well as subduction megathrust earthquakes [...]

Observed ground motion records were analyzed for estimating site effects in Lima Metropolitan Area, Peru in the frequency range from 1.0 to 20.0 Hz. The spectral inversio [...]

In this study we carried out long-period ground motion FD simulations during a middle magnitude earthquake using the 3D basin model by some previous studies in the Fukuok [...]

We propose an inversion method for estimation of a 1D S-wave velocity structure of deep sedimentary layers using S-wave parts of earthquake records for evaluating site am [...]

Recently, the number of monitoring reports of seismically isolated building is gradually increasing. In this paper, a long-term dense monitoring system of seismically iso [...]

The strong motion data on Monzen-machi Town, where is the one of the most severely damaged area, could not be obtained during the Noto Hanto Earthquake in 2007. This area [...]
